Hi jeff which heat sink (were) on the board i can solder (cb fixer) never a tv.need to know were to bleed voltage off.(fear) just in case, also a site to get them from and how many IC"s i've been reading some say 1 orther's say two??.but my problem is similar, the Blue stays still,only the yellow moves some what Red is impossible. is it possible to remove the top back section also without hindering the mirror. all advise would be appreciated.

Difficult.. if you have no solder experence ...dont try it.. depending on your exp..ok.. as a tech thats a everyday thing.. they are two big black ic mounted on big heat sinks...with a bout 20 pins that can be difficult to get lined up. When you replaced them however ..there is a few other things to check. fuses. and output resistors. just getting the boards out can be difficult.

Probably started as a bad solder connection but if it's blowing fuse FU106 now, you're probably in for a new set as that usually means your convergence IC's are bad along with a pair of darlington transistors that's mounted to the heatsink nearby. With the age of the set it may not be worth the trouble. If no fuses are blowing, you could still have a bad solder connection near the Switched Mode Power supply transformer. If that isn't it, you could have a bad High Voltage Block and you may end up having to replace the deflection board as well thank you Pioneer.

A convergence IC has burned out. If I remember correctly, those Pioneer sets have one huge convergence IC, but that IC only has 5 channels in it so they use another smaller dual STK IC and one half of it is used for the 6th channel and the other half is the vertical output. Look on the convergence board, find the blue convergence jack, identify the blue horizontal channel, follow the traces and replace the IC handling the blue horizontal channel.

This is actually a common problem with this unit and one that Pioneer is aware of...
Over time the feed resistors in the convergence circuit change in value and the convergence ICs begin to fail, placing more of a load on the power supply than necessary and stressing components in the SMPS.
The fix; Pioneer recommends upgrading the convergence IC's from STK392-110 to
STK392-180, change all resistors in the convergence circuit that have changed in value and replace the power supply to repair the unit.
